Home to a life flight helicopter, the Mayo hangar needed a reliable door. Our bottom rolling hangar door was the perfect answer. The HU400 model, a four section, uni-directional system, was chosen with a northern stack layout. Each door section was 52'-6" wide by 18'-0" high. The doors are power operated and given it is located in Minnesota, they choose to have a de-icing system put in for the bottom rails.
